Application filed October 7, 1910. Serial No. 585,852.

the locomotive without taking out or dropping the driving wheels,disturbing connecting rods or brake rigging or taking down the framehinder or pedestal brace.

My invention will be best understood by reference to the followingdescription when taken in connection with the accompanying illustrationof one specific embodiment thereof, while its scope will be moreparticularly pointed out in theappended claims.

In the drawings which form part hereof: Figure 1 is a view showing adrive axle in section and my improvement in side elevation. Fig. 2 is aview, partly in plan and partly in section, of the same minus thespring, and also showing a portion of the adjacent drive wheel. Fig. 3is a detail horizontal section taken in the plane indicated by the line3-3 of Fig. 1. Figs. 4 to 15 are detail views of elements comprised inmy improvement and hereinafter specifi cally referred to.

Similar numerals designate corresponding parts in all of the views ofthe drawings, referring to which:

1 is a pedestal frame. 2 is a pedestal brace or frame binder. 3 is aspring, and 4 is a spring-saddle; the said parts being relativelyarranged as shown so that the saddle 4 is capable of being shifted toone side when weight is taken off the spring.

5 is a locomotive drive axle; 6, a drive wheel thereon, and 7, a bearingbox, arranged in the frame 1 and receiving the axle 5, and flanged atits inner end, as lndicated by 8, butnot flanged at its outer end. Thesaid box 7 is equipped with the usual removable section 9 disposed aboveand in contact with the axle 5, and is also furnished with a cellar 10,shown in detail in Figs. 8 and 9, which cellar is detachably secured tothe box through the medium of a bolt 11, Fig. 6, and by reason of itslateral projections 12 being arranged in recesses 13 in the box.

. In the upper portions of its sides 14 and near its outer end the box 7is provided with grooves -15 which extend downward from its upper end,and in said upper end the box is provided with a key-seat or groove16,alined with and extending between the grooves 15, and 1salsoflprovided with a groove 17 de 0rd 2. bearing for the. innerlegsigned to, a

o saddle 4, a central depression 18 adapted to receive lubricant andconnected through ducts l9wwith the inner side of the section 9, andauxiliary depressions 20 connected through intermediate ducts 21 withthe depression 18 and through other ducts 22 with the, sides 14 of thebox.

23 is a shoe, shown in detail in Figs. 10-12. 24 1s a wedge, shown indetail in Figs. 13 to 15, and 25 1s a key, shown in detail in theperspective Fig, 5. The shoe 23 is channeled at 26 to receive one sideof the frame 1 and is connected thereto by the bolt 27, extendingthrough the frame side and threaded at 28 into the shoe. It will also beunderstood by comparison of different figures that the shoe 23 isprovided with a facing 29 '(of Babbittmetal, tin, brass or othersuitable material) that forms a bearing surface for the inner side ofthe drive wheel 6, and is also provided with a groove or key-seat 30,Figs. 2 and 10, and a lubricant container 31, the latter being connectedthrough a duct 32 with the exposed side of the facing 29. The wedge 24is channeled at 40 to receive the corres ondingly tapered side 41 of thepedestal rame 40 to which it is connected by bolt 42, and is providedwith a facing 43, an oil container 44 and duct 45leading therefrom, anda key-seat or groove 46, Figs. 3.

and 13. t It will also be noted by comparison of Figs. 1 and 15 that thewedge 24 is recessed at 47 for the swivel connection of the bolt 48which is threaded through the pedestal brace 2 and is equipped with a jam nut 49. The key 25 is removably arranged in the key-seat 16 of thebox 7 and is provided in its upper side with a, recess 50 to receive theouter leg of saddle 4, and is also provided with depending endportions51 and 51 the portion 51 being arranged in the coincident key-seats l5and 30 of the box 7 and shozff'23, respectively, and the portion 51being arranged in the coincident key-seats 15 and 46 of the box 7 andwedge 24, respectively.

The key 25 arranged as shown in Fi e. 1-3 serves to hold thebox 7 inposition while axle 5 and taken out.

in use, and is held firmly in place by the saddle 4: and the weightimposed thereon,

To remove the box 7 from the locomotive, it is simply necessary to takeweight off the spring 3, shift the saddle 4 to one side, and

' lift out the key 25, whereupon, by reason of the box 7 being unflangedat its outer end, the said box can be moved inward on the Then the shoe23 and wedge 24 may also be removed without disturbmg other parts.

It will be gathered from the foregoin "that the facings 29 and 43 of theshoe ant wedge, by reason of being built out on the "1:15

sides of the shoe and wedge, are adapted to take the lateral thrust andwear of the drive wvheel 6, and that the key is adapted to preventendwise movement of the box 7, the

said key being held against movement in said direction by the shoe andwedgewhich straddle the sides of frame 1 as before de While I have shownand described oneform of my invention, it is to be understood that I amllOtwllHlltQd to the details or the form or relative arrangement ofparts disclosed, but that extensive modifications may I be made therein,without departing from th spirit thereof.
